Do the same on the pass. side of the truck. Then drop the fusebox and any other sensors you will need so that they sit underneath the battery tray out of sight but still accessable if needed.
After that i filled all the old holes that the sensors used to be in and everything else that i removed, spot welded them and then some bodyfiller to smooth it all out, Prime, Paint and your bay is tucked and shaved.
Im also tucking the brake lines and everything else so it will be just motor and carb in the bay, but im still working on figuring out where to relocate alot of the other stuff. But for now all the wires are tucked. Be sure to wireloom and elec. tape the harness that runs outside because it will be exposed to the elements. I dont plan on driving mine in any bad weather or anytime but summertime so i wasnt all to concerned about the wires being tucked up inside the fender.
